  1. A

    Keep the original ranking unless the patient develops a new symptom

  1. A

    Choose the diagnosis that matches the first familiar pattern and stop considering alternatives

  2. B

    Consider only diseases previously seen in patients with the same main symptom

  3. C

    Ask what mechanisms could produce the observed problem, including causes that do not fit a classic pattern

  3. C

    Ask only questions that confirm the most familiar diagnosis
